Abstract:
Described herein are variants of H. jecorina CBH I, a Cel7 enzyme. The present invention provides novel cellobiohydrolases that have improved thermostability and reversibility.
Abstract:
An evolvable production strain of B. subtilis exhibiting continuous or high level expression during protein evolution is described. An evolved Bacillus subtilis pstS promoter facilitates screening and production of secreted proteins.
Abstract:
Described herein are methods for increasing the amount of protein secreted by a cell. In one case, a cell is provided which contains a heterologous nucleic acid encoding a protein having unfolded protein response modulating activity and a heterologous nucleic acid encoding a protein of interest to be secreted. In one case, the protein having unfolded protein response modulating activity is selected from the proteins selected from the group consisting of HAC1, PTC2 and IRE1. The protein of interest can be any secreted protein such as a therapeutic or an industrial enzyme. For example the protein can be selected from the group consisting of lipase, cellulase, endo-glucosidase H, protease, carbohydrase, reductase, oxidase, isomerase, transferase, kinase, phosphatase, alpha-amylase, glucoamylase, lignocellulose hemicellulase, pectinase and ligninase.
Abstract:
The present invention is related to glucoamylases having at least 80% sequence identity to a Trichoderma glucoamylase having the sequence of SEQ ID NO: 4 and biologically functional fragments thereof. The invention is also related to DNA sequences coding for the glucoamylases, vectors and host cells incorporating the DNA sequences, enzyme compositions and methods of using the glucoamylases in various applications.

Abstract:
Biomolecular conjugates are provided which comprise the conjugation product of a repeat sequence protein polymer and at least one active agent. Additional aspects provide methods for their manufacture and various industrial and consumer applications.
Abstract:
A novel DNA is provided which encodes an enzyme having phytase activity isolated from Trichoderma. Also provided for is a method of isolating DNA encoding an enzyme having phytase activity from organisms which possess such DNA, transformation of the DNA into a suitable host organism, expression of the transformed DNA and the use of the expressed phytase protein in feed as a supplement.
Abstract:
Disclosed are variants of Humicola grisea Cel7A (CBH1.1), H. jecorina CBH1 variant or S. thermophilium CBH1, nucleic acids encoding the same and methods for producing the same. The variant cellulases have the amino acid sequence of a glycosyl hydrolase of family 7A wherein one or more amino acid residues are substituted.
